I guess, we don't need to mimic Skype's proprietary protocol, because
that would create patent-related problems in some parts of the world.

What we need though, that's a WORKING and robust NAT traversal
technique, be it in Ekiga or any other SIP-based softphone. Because
that's what prevents them for working reliably everywhere. This is an
interesting research project:
